The results of simulation of the heavy cloud dispersion in the atmospheric boundary layer are presented. The model of the turbulent dynamics of the heavy cloud is described. The Favre - Reynolds averaging procedure is used, that results in the less complicated form of equations than the Reynolds averaging procedure. The first-order turbulence model is applied for the calculation of turbulent fluxes and stresses. The numerical algorithm of the problem solution is briefly described with use of the the conservative implicit finite-difference scheme. The splitting method upon the space directions and physical processes is used. The results of calculations are compared with the results of laboratory and field experiments. The analysis of the energetics of the heavy gas dispersion processes is given.
